Update: Using the System

This blog post summarizes the usage of our attendance tracking system. We have been testing it in order to make it usable for the study, and to keep information safe from leaks.

- it must be usable
- it must keep information safe from any unintended accesses (accidental or penetration, some subversions)

This should make students more willing to participate. The basic procedure for students is:

- download from Play Store (we'll support both x86 and ARM devices)
- or download to their laptop (which can run Linux, Windows, or OSX)
- on initial startup, students associate a password with their anonymous research ID
- students will use this password-ID pair to login on every startup
- students may click the bottom-most button until they reach the attendance verification screen
- students may review their list of classes and corresponding attendance records
- they finish by gathering and sending attendance evidence

The procedure for instructors is:

- download QR or Pattern image
- or copy pin or password
- display this code in a prominent location
- wait for students to register their attendance
- download attendance records as a CSV file from the server

We'll refine this process before we begin our experiment.
